Thanks Charley. Those stripes are very interesting. Do you know of any original 67 or 68 cars with a big block and a manual transmission that we can check the driveshafts on? I believe they are not they same length as other 67s and 68s.

Kurt and Ed, I think we might be getting close to having enough information to feel comfortable posting those numbers.

Hi, I have an original 23,000 mile 69 Z/28. My particular driveshaft has a part number stenciled on it. I don't see any others on this thread with anything similar, other than what Bertfam posted. The car is a Los Angeles build, 03B, 302 with M21. Photos:

I hope this will be some help in your research. I look forward to participating in this forum. Bob

That's a Service replacement prop shaft, used for all except TH400 - they were furnished without the yoke and U-joints (unlike the production prop shaft assembly, which included the yoke and U-joints).

Well it depends. What year and what application driveshaft are you talking about? TH400 yoke is different than others. All 69 Camaro driveshafts were 49.56 inches long but yokes were different based on application.
